发明名称 Detecting and Tracking Touch on an Illuminated Surface Using a Mean-Subtracted Image
摘要 A method for touch detection performed by a touch processor in an optical touch detection system is provided that includes receiving an image of an illuminated surface included in the optical touch detection system, wherein the image is captured by a camera included in the optical touch detection system, subtracting a background model from the image to generate a mean-subtracted image, identifying a set of candidate touch locations in the mean-subtracted image, classifying the candidate touch locations in the set of candidate touch locations to generate a set of validated candidate touch locations, and outputting a set of final touch locations determined from the set of validated candidate touch locations.
